Enjoybot 36V LiFePO4 Lithium Trolling Motor Battery Set - 3 batteries

The main difference between a Group 24 and Group 31 battery is their physical size.
Group 24 batteries are smaller, typically measuring 10.5" L x 6.19" W x 8.88" H. They are ideal for lighter-duty applications like small boats, RVs, and backup power systems.
Group 31 batteries are larger and provide higher capacity, making them suitable for heavier-duty applications such as larger boats, commercial vehicles, and high-demand RVs.

A self-heating lithium battery can be beneficial if you plan to charge your battery in cold environments. The self-heating feature ensures that the battery will charge properly in temperatures as low as 32°F (0°C). If you live in a region with cold winters or expect to use your battery in freezing conditions, a self-heating battery may be what you are looking for.

When the temperature drops below 32°F (0°C), charging is automatically suspended, and the built-in heating pad activates to warm the battery. At this time, the charger powers only the heating pad, ensuring safe operation. Once the temperature reaches 41°F (5°C), heating stops, and charging resumes, ensuring optimal battery performance in cold conditions.

These two features address the challenge of charging LiFePO4 lithium batteries in cold weather.

Low temperature protection automatically shuts off charging when the temperature drops below 32°F (0°C). To resume charging, simply place the battery in a warmer environment, and charging will be restored once the temperature rises to 41°F (5°C).

Self-heating enables charging at low temperatures by activating the heating mode when the temperature falls below 32°F (0°C). Charging will resume automatically once the battery reaches an optimal temperature.

Enjoybot 36V lithium battery set is compatible with 36V trolling motors offering 100-120 lbs of thrust

The charging range for the 36V battery pack is 42.6V to 43.8V. We offer both a 43.8V 12A charger and a 43.8V 20A charger for your choice. Additionally, to regularly balance the battery pack voltage, you may need a separate 14.6V 20A charger for charging each individual 12V battery.
